Are you building a hidden room with a secret door, or maybe a safe room?
When you are installing a fully concealed jib door, you want to hide the door hardware too — and you have to think about hiding the hinges, tongue mortese strike plate, but also about the door handle or door knob too. Figuring out the door handle for different types of hidden door is one of the biggest challenges for any interior designer or manufacturer.
There are multiple methods for opening the door without the traditional door handle including a push touch latch we can use for Dorsis Fortius, our concealed doors. Your first question should be this: Is the door inswing or outswing?
When Belgian designer Stefan Vanderick introduced the first generation of the No-Ha invisible door handle, it was a true breakthrough. The combination of a magnetic lock and a handle (basically a pressure plate) created the first invisible door lockset. Today, No-Ha 2.0 represents a lockset that lets you open and shut doors while the "door handle" element is fully concealed and in the same finish as the door panel and walls.
The cover plate is interchangeable, fully customizable and prepared to receive either paint or be bonded with additional material. At Angelbau, we typically custom paint or powder-coat the plate of the No-Ha invisible handle in the same color as the door to make it disappear. However, the plate can also be in contrasting color, and for unique conditions, such as hidden doors in wood panel walls, we frequently add a layer of grain-matched wood veneer so that the invisible handle blends in.
The No-Ha handles are made in Italy by Bonaiti, but you'll find them sold white-labeled as RocYork.
The NoHa invisible lock can be configured for passage or privacy functions. However, the privacy version has a visible thumbturn which somewhat collides with its key design proposition of flush look.
No-Ha is available as a collection:
